STUDY DESIGN: Pilot, multicentre randomised clinical trial (RCT). OBJECTIVES: Assess viability of performing a definitive RCT and compare preliminary effects of movement pattern training (MoveTrain) and strengthening/flexibility (Standard) to improve function in people with chronic hip-related groin pain (HRGP). BACKGROUND: To determine the best physical therapist-led intervention for patients with HRGP, we must understand treatment effects of different treatment modes. METHODS: Forty-six patients (17M:29F; 29 +/- 5.3 years; body mass index 25.6 +/- 6.3 kg/m2) with HRGP were randomised. MoveTrain included task-specific training to optimise biomechanics during daily tasks. Standard included strengthening/flexibility. Treatment included 10 visits/12 weeks and home exercise programme (HEP). Primary outcomes for feasibility were recruitment, retention, treatment adherence and treatment fidelity. Secondary outcomes were patient-reported function (Hip disability and Osteoarthritis Outcome Score (HOOS)), lower extremity kinematics and hip muscle strength. RESULTS: We achieved target recruitment, and retention was excellent (91%). Patient session attendance was high (93%); however, reported HEP adherence (62%) was lower than expected. Physical therapists' adherence to treatment protocols was high (90%). Patients demonstrated high treatment receipt; 91% of exercises performed were rated independent. Both groups demonstrated clinically important improvements in function (HOOS) and muscle strength; however, there were no between-group differences (HOOS subscales, p >= 0.13, strength, p >= 0.34). Compared with Standard, MoveTrain demonstrated greater reductions in hip adduction (p = 0.016) and pelvic drop (p = 0.026) during a single leg squat. No adverse events were noted. CONCLUSION: Our experience in completing this RCT confirmed that a larger, multicentre RCT is feasible and highlighted modifications we will implement to optimise the future RCT.
